It's hard to qualify what "Best" means. Best means different things to different people, depending upon their emphasis on looks, price, durability, gas mileage, comfort, performance, trunk space, and other factors that people might value.

Just did the Chicago Ford Challenge and was quite impressed with the C-Max Hybrid (they also have a Hybrid/plug-in version called the Energi). I was quite impressed with the mpg results, acceleration, power and mostly the interior room plus the fit & finish. To make things better "MADE IN THE USA". This may be my replacement vehicle....definately one to consider!

Its easy to have one's own personal opinion on things. In the opinion of people who actually put down their own money to buy a car, instead of just providing "armchair opinions", it appears to be the Toyota Prius, which while not the first one on the market, has been on the market continuously, longer than the others.

As more manufacturers begin to sell hybrid models, some other very good ones are sure to begin selling in quantity.

Here in Orange County, California, the Prius is extremely popular; you see them everywhere.
